Serum Insulin Concentrations are Lower in Daily Drinkers Compared with Abstainers

A new report1 examining 883 randomly selected Hispanic and non-Hispanic white men and women aged 65 and over (The New Mexico Elder Health Survey) was published recently. The researchers found that the participants who consumed alcohol daily had significantly lower fasting and 2-hour postglucose serum insulin concentrations compared with those who abstained from alcohol, after adjusting for serum glucose concentration, gender, ethnicity, age, and body mass index. They conclude, "Abstainers with their relative hyperinsulinemia appear to be more insulin-resistant than daily moderate drinkers. This difference in insulin sensitivity may explain the lower prevalence of diabetes in drinkers compared with abstainers observed in various epidemiological studies."
